A PopGrip sticks flat to the back of your phone, tablet or case with its rinsable, repositionable gel. Once extended, a PopGrip becomes a media stand for your device, a photo or texting grip, or lower it for a video chat. *For best results, use in conjunction with a phone case. The PopGrip's gel sticks to most materials. It may have issues sticking to silicone, waterproof, and textured materials, like leather.
